OUR SOLAR SYSTEMby Dominic Fabbri
  • Our solar system has two groups of planets, the inner planets and the outer planets.
  • Our solar system has 8 planets and 1 dwarf planet.
  • Our solar system contains a variety of objects. These include planets and moons, as well as asteroid, which are small and rocky.
our sun
  • Our Sun is the center of the Solar System.
  • The Sun’s diameter is more than 1,000,000 kilometers.
  • It is the source of energy on Earth, and without it life could not exists.
  • Mercury is a small, rocky planet.
  • It is covered with many craters.
  • The planet is about the size of Earth’s moon.
  • Venus is the second planet from the sun.
  • The planet is also the brightest planet in the solar system.
  • Venus is the third brightest object in Earth’s sky. Only the sun and moon appear brighter.
  • Earth is the third planet from the sun.
  • This planet is the fifth largest.
  • It’s the only planet known to have life and the only planet whose surface is mostly water.
  • The nickname Mars has is the red planet.
  • Mars has huge dust storms that can last for months.
  • Scientiststhink that at one time Mars may have had water on the planet.
the asteroid belt
  • The asteroid belt is located between the planets Mars and Jupiter.
  • More than 7,000 asteroids have been discovered in the asteroid belt. Several hundred more are being discovered each year.
  • This planet is the largest planet in the solar system.
  • Jupiter has at least 63 moons.
  • For more than 300 years, a gigantic hurricane- like storm called the Great Red Spot has raged on Jupiter.
  • Saturn has rings that are visible from Earth through a telescope.
  • Its atmosphere is mostly hydrogen and helium.
  • Saturn has at least 31 moons.
  • Uranus rotates on its side as it orbits the sun.
  • The planet has at least 27 moons.
  • Uranus is one of the gas giants.
  • Neptune’s atmosphere is mainly made of hydrogen and helium.
  • It is one of the windiest planets in the solar system.
the dwarf planet pluto
The Dwarf Planet Pluto
  • Tiny Pluto has a rocky surface covered with nitrogen, ice, and small amounts of methane and carbon dioxide ices.
  • From the surface of Pluto, the sun looks like another bright star in the sky.
  • Pluto’s moon is about the same size as Pluto itself.
the galaxy
The Galaxy
  • A galaxy is a huge system of gases, dust, and stars.
  • Galaxies contain billions of stars. Our sun is on the edge of the Milky Way galaxy.
  • A comet is a ball of rock, ice, and frozen gases.
  • As a comet’s orbit brings it close to the sun, the sun’s heat may turn some of the frozen matter into gas.
the universe
The Universe
  • The universe is everything that exists in space.
  • There are many different galaxies in the universe.
other dwarf planets
Other Dwarf Planets
  • There are officially 5 recognized dwarf planets in the solar system. They are Pluto, Eris, Ceres, Haumea, and Makemake.
  • There are another 6 objects in our solar system that are almost certainly dwarf planets and there may be 10,000 altogether.
  • A telescope is an instrument that is used to better view the sky.
  • The first telescopes were all refracting telescopes.
  • Constellations are a group of stars that create an imaginary picture in the sky.
  • In ancient times, people often gave these constellations names .
other stars
Other Stars
  • Here are the names of some other stars, Procyon, Sirius, Barnard’s Star, Alpha Centauri, and Ross 154.
  • The 3 closest stars to our solar system make up the star Alpha Centauri.
